SPECIFICATION forming part of Letters Patent No 311,850, dated February3, 1885.

7 Application filed January 3, 1882. Renewed September 2-2, 1884. (Xmodel.)

To all whom, it may concern Be it known that I, EVERETT P. RICHARD- soN,of Lawrence, county of Essex, State of Massachusetts, have invented anImprovement 5 in LastingMachines, of which the following description, inconnection with the accompanying drawings, is a specification.

In the machine herein described the action of the gripping jaws ordevice is substantially that practiced by hand-lasting with nippers,

with, however, the advantage of simultaneously stretching and drawingthe edges of the upper about the last from two opposite points,

and from opposite sides of the last toward the center line of the bottomof the last.

My invention consists in a nail-driving le ver directly actuated in onedirection by means of a treadle, and in the other direction by means ofa spring. 7

My invention also consists in upper gripping jaws or devices to engageand draw the upper by its opposite edges about the last, combined withmechanism at each side of the last, and cooperating with the said jawsor devices, to automatically drive nails or fastenings into the saidupper and inner sole to confine them together.

My invention also consists in a novel method of lasting, as will behereinafter described and claimed.

My invention also includes an inner-sole presser, which is located nearthe jaws which grasp the upper, and which, interposed between the edgeof the upper and inner sole,

5 holds the latter down snugly upon the last while the upper, near thepresser, is drawn and nailed, and also in organizations of mechanicalelements, as will be hereinafter fully set forth in the claims at theend of this specifi' 4o cation.

Figure 1 represents in side elevation a sufficient portion of alasting'macliine to illustrate my invention; Fig. 2, a front elevationof Fig. 1; Fig. 3, a section on the dotted linexx, (see Fig. 2;) Fig. 4,a detail to be referred to; Fig. 5, anenlarged view of the rearside ofthe upper part of one-half of my machine; Fig. 6, a view of Fig. 5 fromthe right. Figs. 7 and 8 are sectional details taken through the shanksof the jaws and their friction device, and through the lever which,pivoted upon one jaw, actuates the otherjaw to cause the two jaws toattimes move separately and thereafter together; Fig. 9, an enlargeddetail of the acting or forward ends of the gripping-jaws to receive theupper; Fig. 10, a detail to be referred to; and Fig. 11, a detailshowing the addition to the machine of an inner-sole presser, omittedfrom the other figures to avoid confusion of parts.

The base or standard 66, of suitable height, has at its upper end aplate, a, which has se cured to it the two standards 12 b, which receiveand guide the gripping-jaws and the nail-driving mechanism, to bedescribed. Each standard, its upper gripping devices, and nail or tackdriving mechanism being alike, I need to specifically describe but oneof them. The standard I) at its upper end has a cross-head, b, in whichis a horizontal guideway as shown in Figs. 1, 6, 7, and 8, that receivesin it the shanks of the two upper-gripping jaws c d. The shank of jaw dis recessed along one side to receive the shank of jaw c, and is slottedat d (see Fig. 5) to receive through it the friction device e, shown asa round rod at 7 5 tached to the upper end of a spring-arm, 0, connectedwith the rigid orfixed part b. This friction device, by its action onthe shank of jaw c, prevents its being moved by simply the frictionagainst it of the moving jaw d. The jaw c is provided at one side (seeFigs. 5 and 8) with a stud, c, which, extended through a slot, 2, in theshank of jaw (1, serves as the fulcrum for the short jaw operating audcarrying lever 0 the lower end of which is en- 8 gaged and moved by thejaw-actuating lever f, pivoted atf. The lever c isprovidedwith anelongated slot, as shown at Fig. 5, at a point between its fulcrum andits free end, and receives in the said slot a stud, (1 secured 0 to theshank of jaw d. The acting front end 3 ofjaw c is made as a hook, with,preferably, a serrated inner face, as shown in Figs. 5 and 9, to engagethe upper at the inner side of its edge, or between the upper and theinnersole, while the front or acting end 4 of jaw (I, also preferablyserrated, is made wedge-shaped, to come against the face or outer sideof the edge of the upper and grasp the said edge between the twoportions 34, the said parts once closed upon the edges of the upperholding the said usual construction, held on a spool, pivoted to thestandard 9, rising from the plate 9.

This string-nail material, in common'use in nailing-machines, passesunder a detent or shield, h, also common to other nailing-ma chines. Theplate 9 atits front end has on its groove asmallsteel cutting-block, 9which serves as one member of the cutting device, which severs each nailas it is driven from the next nail back of it in the string of nails.The head of the second nail back of the one last driven is acted upon,and held from moving backward by the detent h. The other member of thecutter is the steel block 70, which forms the main part of the nail-driver, or that part which directly engages the head of the nail. Theblock 70 has at its upper edge a rib, b, which enters a correspondinggroove in a lever attached to the driver-carrier, (herein shown as alever, if.) This lever is pivoted at k to the plate 9. The block it isheld upon the lever somewhat loosely by the screw 7 and the pressure ofthe spring 18, such loose conneetion permitting the block to moveoutwardly, during the upward movement of the driven.

. To limit the descent of the lever 7c when thrown down by spring Z todrive a nail, the plate 9 has extended from it a part, m, pro vided atits upper side with a yielding cushion, W, to lessen shock and noise.The spring I at its upper end is connected with the rod 1,- which ispivoted to the stud Z" of the ear Z" of lever and at its lower end thespring I is joined with the adjustable yoke a, fixed upon the rod asecured to the bracket a of the standard a. The lower end of rod Z(shown in section, Fig. 3, and in detail, Fig. 4) has a projection, 8,(see Fig. 4,) which rests upon a shelf or projection, g, of the crosshead p ,car ried bythe slide-r'odp, having on it agrooved cross-head, pwhich receives a roll or crankpin, 12 on the disk 9" 'of anintermittingly-ro- .tating power-shaft having fixed upon it one member,1, of a. friction or clutch pulley, the other or loose member, r aboutwhich the driving-be lt will extend, being under the control of atreadle and intermediate devices, whereby the clutch-pulley may beseparated and 70 the movement of the disk and crank be stopped aftereach complete. revolution, and remain at rest until the clutclrpulley isagain engaged by the operator. The lower ends of rods Zare kept upon theshelves 9 of the crosshead p by the inclined positions of the springs Z,and as the cross-head is raised the said rod is lifted to lift thedrivenleverslc as in Fig. 5, and strain the springs Z,- but as soon asthe cross-head reaches a certain position in its upward movement, atwhich time the jaws are supposed to have reached their farthest forwardpositions, with the edges of the upper between them, the ends of therods are acted upon by the pawlsp, pivoted upon the yoke 12, (the saidpawls being then brought into nearly horizontal position,) whichp'ushthe said rods from the shelves 9aiid allow the springs Z to act andthrow down the arms is" and block is, the latter engaging the head of astring-nail and driv- 9o ing it into the upper and into the inner soleon the last at one side of the jaws, which then grasp and holdit. Theblock'k in its downward movement against the head of the nail,

as the block arrives opposite the steel edge 9 before referred to, cutsthe nail, the body of which has been partially driven,and sev'crsit fromthe string of nails. The block it, when driving anail, moves the stringof nails with it, and thus acts to feed the nail-string forward. IO 3:The wedge s at the upper end of the bar 3'', pivoted to the lever 8 andhaving its fulcrum at s, as the bar 8 is moved in the direction of thearrow, acts upon the hub of the loose member 1' of the clutch-pulley andcauses the :05 members w r to be forced together to rotate the disk rand crank-pin once. The levers".

is acted upon by a spring, 22, (shown only in Fig. 1,) which places thelever and wedges in such position that the clutch-pulley parts are notpressed toward each other with sufficient force to run together. Thefree end of thelever s", acted upon by the said spring 22, is held up,as shown inFigJl. The link '8, hav

ing a projection, 15. located at one side of it, I 15 and just abovethefree end of lever 8 isjoined with a treadle, if, having its fulcrumat t on the treadle-carrying arms t", which have their fulcrum at t, aspring, 1, rigidly connected at one end with the standard a, serving toI20 keep the arms t" lil'ted, as in Figs. 1 and 2, and with the pin 17ot' the link 8* against the bracket a A spiral spring, a, or it might bea weight, keeps the link pulled in such direction that the projection 15will catch over the end of lever 5 The pin 16 controls the point towhich the lever 8* and the front end of the treadle t may descend. Thearms t have connected with them the links or connecting-rods to, whichat their upper ends are 1 0 joined with the lower ends of the'jaw-movinglevers f, pivoted at f,'the said levers being adapted at their otherends to engage the ends oflevers c.

Referring to Fig. 5, thefront'ends, 3 4, of the horizontally-movablejaws or grippers c d areshown asopened to receive between them the edgesof the upper. Both pairs of these jaws atoppo'site sides of the last andupper to be lasted are in like condition, and have like movements givento them simultaneously. The edge of the upper-having been placed betweenthe endsof the said jaws, the operator, with his foot upon the treatleIt, will depress or push down the arms t from their full to their'dottedline position, leaving, however, the treadlet on its dotted-lineposition,which will so actuate the levers f and 0 as to produce thefollowing movements in thejaws 0 d, viz: The leverfwill move the lowerend of the lever c to the right, (see Fig. 5,) and cause lever c ,by itsaction on'the pin or stud d ofthe shank ofjaw d ,to carry the said jaw dforward,

, thejaw 0 being then held by the friction device 6 until its end 4 ismade to clamp the edge of the upper firmly between it' and the end 3 ofjaw 0. At about this time the lower end of the lever c has beenswungtoward the right about its fulcrum 0, connected with the shank ofjaw 0,so that it occupies a position substantially as indicated in dottedlines, Fig. 5, at which time the centers 0, d, and f will be in suchline with relation to each other that further movement of leversf and 0will cause the two jaws c d to be moved forward in unison, they clampingor gripping the upper firmly between their parts 3 4, and drawing andstretching the upper about the last by a direct pull thereon fromsubstantially opposite points and from opposite sides of the last, thesaid jaws passing over the innersole upon the bottom of the last andcarrying with them the edges of the upper,to be automatically nailed orfastenedto the inner sole while so held by thejaws. Thedriver-leverhavingbeen thrown down to drive astring-nail, as will bedescribed, bythe spring Z, after the action .of the pawls on the rodsl,the arms f are permitted to rise, and the leverf is moved in theopposite direction. At first the jaw dis started by itself, thejaw 0being held bythe friction device 6, and moved back far enough to releasethe edge of the upper, after which the two jaws are carried backwardtogether, and the last and upper thereon moved,preferably by hand, farenough to enable the jaws to be again closed upon that part of the edgeof the upper to be next clamped and drawn over upon the inner sole,as just described. During the time that the jaws are opened or separated andthelast, with the upperon it, is being moved for the next operation, theedges of the upper are kept between thejaws, and jaw c is moved back farenough for the edge of the upper to come in contact with the part 24 ofthe jaw c.

In Fig. 1 the wedge s is not lifted quite enough to cause the operativeengagement of the clutch-pulley, and the crank-pin 12 is substantiallyin the same horizontal plane as the center of the shaft on which is thedisk 7", that carries the crank-pin 12. As the arms t are depressed intothe dotted-line position, Fig. 1, to close andmove the jaws forward, thefront end of'treadle t is kept elevated by the greater pressure of theheel on' the treadle, so,as to keep rod .9 lifted and the pin 17 againstbracket a", andoon-se'quently when arms-f are down, as in dotted lines,the treadle t is as in dotted line. The upper having been drawn overupon the inner sole by the jaws *and to the satisfaction of theoperator, he will turn the treadlet, push down its front end, depressthe rod 8, and cause its projection'15 to turn the lever s lift the barand wedges, and force the clutch-pully parts so closely together as tocause the loose but running part r to pick up the fastpart i" and turnthe disk r and crank-pin 12 to completely lift the partiallyliftedcross-head 10 further strain the'springs Z, push off the links Z, andpermit the springs l to operate the driver'lever and drive a nail, afterwhich the motion of disk r will be continued until the cam or thereonstrikes the upper endof rod '8, pushes it. outward, and removesprojection '15 from above the lever 8 when the disk 1", having made onerevolution, will stop, a suitable pawl, 00 engaging a notch in the saiddisk, as shown in Fig. 2, to hold it I at rest. When I the disk stops byreason of lowering the wedges, the cross-head 19 has been liftedsiifliciently to elevate the lever to nearly its highest position fromwhich it started when the clutch-pulleywas engaged, as described. Thejaws are closed and moved forward by manual power applied through thetreadle by the foot of the operator, and may thus be made to stretch theupper more or less, according to its particular needs and strength; butthe nail-driving mechanism is operated at the proper time automaticallyto drive the nails into the upper. The drivcrlever, being pivoted uponthe jaws,always occupies the same position with relation to theupper-grasping portions of the jaws, no matter how far they are movedover, the edgeof the inner sole, which is preferable to employing jawsto pull-the upper forward and place it under a stationary nailtube orpost in which a driver is made to reciprocate, as. has been doneinothermachines. Theusual'innersole, (see Fig.- 11,) a part of which is shownat'25, and which will be laid in the last 26, all as usual, is apt tobecome lifted or curled up if very soft; but to avoid this I haveattached to the jaw c by screws 27 and 28 a standard, 29, to the upperend of which at 30 I have pivoted the inner-s0le presser 31, the lowerend of which is curved, as shown, to form a foot to bear upon the innersole near its edge and keep it down upon the last, while the end 33 ofthe said presser bears against the edge of the last,- so as not to movethe inner sole laterally.

In this my improved machine the upper is grasped or engaged at twoopposite points, and is drawn and stretched about the last at suchpoints and from opposite directions by a direct pull, each jaw operatingas do pinchers actuated by hand, and then the upper, immediately when itis grasped, is automatically nailed fast to the inner soler After thisthe shoe is moved a little, and the jaws again grasp the edges'of theuppernear where they grasped it when they were last moved forward, andagain draw such adjacent parts of the upper j about the last fromopposite directions, when gradually drawand fit the upper to the curvaa.

the edges of the upper are nailed to the inner soles, as before. Thejawsthus operate successively and regularly on'the upper, apart at atime, along the whole sides of the last, each movement of the jawspartially drawing upon andxstretching parts of the upper, which will bemore fully stretched at'a subsequent operation of the jaws. In this wayI. am enabled, whenstarting, say, from near the toe, to

tures ofthe upper pa'rt of the last.

I am aware thatthe upper has been engaged at opposite sides of thelastby pullers.
